•
Speed of Line: The line speed (in megabits per second) of data transfer.
One of the following appears: 256, 100, or 10.
The recommended setting values are as follows:
◦ 10 is recommended if the line speed is from 10 Mb/s to 99 Mb/s.
◦ 100 is recommended if the line speed is from 100 Mb/s to 255 Mb/s.
◦ 256 is recommended if the line speed is 256 Mb/s and more.
This setting does not take effect on master journal groups. However, if the RAID Manager
horctakeover command is used to change a master journal group into a restore journal group,
this setting takes effect on the journal group.
•
JNL Volumes: A list of registered journal volumes.
Parity Group: Indicates the parity group where a journal volume belongs. ◦
◦ LDKC:CU:LDEV: Indicates the LDKC number, the CU number, and the LDEV number of a
journal volume.
◦ Capacity: The capacity of a journal volume in gigabytes.
◦ Emulation: The emulation type of a journal volume.
◦ CLPR: The number and the name of the CLPR where the journal volume belongs.
•
Mirrors: If the remote command device is assigned to the mirror of XP Continuous Access
synchronous pair in 3DC multi-target configuration, and the mirror ID is 00, all columns other
than mirror ID and remote command device are blank.
◦ Mirror ID: A mirror ID.
This column is blank if the attribute of the journal group is neither Master nor Restore.
◦ Attribute: Indicates the attribute of a mirror ID.
When primary data volumes of a local storage system are registered to a mirror, Master
will be displayed. When secondary data volumes of a local storage system are registered
to a mirror, Restore will be displayed. If Initial is displayed, no data volumes are registered
in the journal groups of a local storage system.
◦ Status: The status of a journal group (or a mirror) in the local storage system. For detailed
information about the statuses, see
“Consistency Status for Split/Suspended XP Continuous
Access Journal Secondary Data Volumes” (page 40) .
◦ CTG: The number of a consistency group to which the mirror belongs.
This column is blank if there is no consistency group.
A consistency group number shown as [01], indicates that the multiple primary and
secondary storage systems share the consistency group.
◦ S/N(LDKC): The serial number of the remote storage system and the LDKC number.
This column is blank if the attribute of the journal group is neither Master nor Restore.
◦ Pair JNLG: The number of a journal group in the remote storage system.
This column is blank if the attribute of the journal group is neither Master nor Restore.
◦ Controller ID: The controller ID (model name that indicates the model) of the remote storage
system. The controller ID for an XP24000/XP20000 Disk Array is 5.
This column is blank if the attribute of the journal group is neither Master nor Restore.
◦ Path Watch Time: The time for monitoring blockade of paths to the remote storage system.
If the status of the mirror where secondary data volumes in a local storage system are
registered is Hold, Holding, or Hold(Failure), this column is blank.
